X → Interval Conversions

This topic provides a reference table for all automatic type conversions to interval, sorted by merit.

Fair Conversions

This section lists all fair conversions to the interval type. A 'Fair' conversion indicates the types involved are closesly related in a data layout sense, though not necessarily in a conceptual sense. For example booleans and integers, or points and vectors. Although these conversions may fail or narrow, it is nevertheless considered decent practice to rely upon them in algorithms.

From	Explanation
angle	Creates an interval from zero to the angle value in degrees.
arc	Extracts the parameter domain of the arc.
circle	Extracts the parameter domain of the circle.
curve	Extracts the parameter domain of the curve.
integer	Creates an interval from zero to the integer value.
integer (big)	Creates an interval from zero to the integer value.
line	Extracts the parameter domain of the line.
number	Creates an interval from zero to the number value.
polyline	Extracts the parameter domain of the polyline.
rectangle	Extracts the parameter domain of the rectangle.
triangle	Extracts the parameter domain of the triangle.

Plausible Conversions

This section lists all plausible conversions to the interval type. A 'Plausible' conversion indicates a non-straightforward, but a still reasonable conversion between two types that share a salient quality, or where one is an obvious sub-type of the other. For example curves and intervals, or points and planes. Any plausible conversion can also be achieved through the explicit use of standard components.

From	Explanation
boolean	Converts false to empty interval, true to unit interval.
complex number	Creates an interval from zero to the real component.

Strange Conversions

This section lists all strange conversions to the interval type. A 'Strange' conversion indicates a peculiar, but occasionally sensible, translation between types. However, it is equally likely that the conversion was not intended and thus represents a mistake in the algorithm design, which is why this conversion level is the default for showing conversion warnings in the Grasshopper interface. Examples in this category include the conversion between colours and booleans, or between circles and triangles. Any strange conversion can also be achieved through the explicit use of standard components.

From	Explanation
vector	Creates an interval from zero to the vector length.

Weird Conversions

This section lists all weird conversions to the interval type. A 'Weird' conversion indicates an exotic relationship between types which is almost certainly unintended on the part of the user. However, very occasionally these conversions make sense and allow the user to avoid the use of several components to achieve the same result. Examples in this category include conversions between planes and integers, or points and intervals.

From	Explanation
point2	Creates an interval from zero to the point's distance from the origin.
point3	Creates an interval from zero to the point's distance from the origin.
